M here and in the sequel denotes various constants, and 1 ?“I the norm of operator T on H. Under assumptions (1 ), (2) the operator A = L + T has a discrete spectrum, that is, every point of its spectrum is an eigenvalue of tinite algebraic multiplicity. If 1 is an eigenvalue of A, then the linear hull of the corresponding eigenvectors is called the eigenspace corresponding to d. Let h, be an e...

both hi being integrable functions, whose smoothness will be addressed later. Very few results are known on the subject, except in two particular cases: two players zero-sum games and LQ games (where LQ stands for linear-quadratic). Indeed, a key step in this kind of problems is the study of the value function u. In the region where u is smooth, its components satisfy a system of HamiltonJacobi...

Holliday junctions (HJs) are cruciform DNA structures that are created during recombination events. It is a matter of considerable importance to determine the resolvase(s) that promote resolution of these structures. We previously reported that C. elegans GEN-1 is a symmetrically cleaving HJ resolving enzyme required for recombinational repair, but we could not find an overt role in meiotic rec...

In bacteria, RuvABC is required for the resolution of Holliday junctions (HJ) made during homologous recombination. The RuvAB complex catalyzes HJ branch migration and replication fork reversal (RFR). During RFR, a stalled fork is reversed to form a HJ adjacent to a DNA double strand end, a reaction that requires RuvAB in certain Escherichia coli replication mutants. The exact structure of acti...

Newly reported normalized cumulant moments of charged particles in ee collisions by the SLD collaboration are analyzed by the truncated modified negative binomial distribution (MNBD) and the negative binomial distribution (NBD). Calculated result by the MNBD describes the oscillatory behavior of the data much better than that by the NBD. PACS number(s): 13.65.+i, 34.10.+x Normalized cumulant mo...

Salmonella Typhi, the causative agent of typhoid fever, is a monophyletic, human-restricted bacterium that exhibits limited phenotypic variation. S. Typhi from Indonesia are a notable exception, with circulating strains expressing diverse flagella antigens including Hj, Hd and Hz66. Hypothesizing that S. Typhi flagella plays a key role during infection, we constructed an S. Typhi fliC mutant an...

In earlier versions of the community discovering problem, the overlap between communities was restricted by a simple count upperbound [17,5,11,8]. In this paper, we introduce the Π-Packing with α()Overlap problem to allow for more complex constraints in the overlap region than those previously studied. Let V be all possible subsets of vertices of V (G) each of size at most r, and α : V × V → {0...

Holliday junctions (HJs) that physically link sister chromatids or homologous chromosomes are formed as intermediates during DNA repair by homologous recombination. Persistent recombination intermediates are acted upon by structure-selective endonucleases that are required for proper chromosome segregation at mitosis. Here, we have purified full-length human GEN1 protein and show that it promot...
